Subject: [PATCH v4] tools/power/acpi: Remove direct kernel source include reference
ACPICA tools trickily uses integer types, and trickily includes kernel
include directory directly, which breaks tools build for some cross
compilers.
This patch improves ACPICA tools build to make it a bit more robust in such
situation by splitting include/acpi into a separate output directory.
This patch also contains OUTPUT/srctree cleanups in order to make above fix
working for various build environments.
Fixes: e323c02dee59 ("ACPICA: MSVC9: Fix <sys/stat.h> inclusion order issue")
